Three concepts · In development
Lose yourself in the workout. Not your count.
A collection of tactile mechanical counters designed to help you track sets and rounds—without another screen.
Athlete Abacus · Concept rendering. Final design and specifications may change.
The insight
Count without breaking concentration.
Mid-workout, a phone is a poor training partner: unlock, open, tap, and the rest period is half gone. Whiteboards need chalk and memory. Memory is the first thing to go when you’re breathing hard.
The simplest counter is a physical one. Finish the set, move something, get back to work. Rig & Rivet is about making that one motion feel considered.
Athlete Abacus · Intended interaction · Illustration
01
Finish the set
Rack the bar, drop the kettlebell, cross the line.
02
One tactile move
Slide a plate, turn a ring or thumb a control. No screen to wake.
03
Back to work
The count is held for you, in plain sight.

02Rotating mechanical set counter
The Dial
One twist. One less thing to think about.
A machined puck with a knurled outer ring. Turn it one step per set; a single window shows the count.

Inside the idea
- Athlete Abacus: Counting you can feel.. A miniature barbell with plate-shaped markers, held in a machined frame.
- Athlete Abacus: One plate per set.. Plate-shaped markers, sized to be moved without looking twice.
- Intended interaction: Finish the set. Slide a plate.. Done on one side, still to come on the other. The count sits in front of you.
- The Dial: A single number.. A single number near twelve o'clock. Nothing else to read.
- Intended interaction: One twist.. Turn the knurled ring one step and the window follows. The center never moves; it is not a button.
- The Wrist Counter: Two digits, on your wrist.. Two mechanical digits behind a single window.
- Intended interaction: Your count moves with you.. Thumb the side control between efforts, never while gripping a loaded bar.
- Three concepts: Three gestures. One idea.. No screens, batteries or apps. One deliberate motion, one glance.

Inside the idea
Three gestures. One idea.
Each concept is built around one deliberate physical motion. Try them below. These are schematic illustrations of the intended interaction, not engineering drawings.

Three ways to keep count.
Design directions, not final specifications. Everything here is subject to engineering.
| Design direction | 01Athlete Abacus | 02The Dial | 03The Wrist Counter |
|---|---|---|---|
| Where it lives | One station: rig, rack or bench | On the rig, at your station | On you, across stations |
| The gesture | Slide one plate | Turn the ring one step | Thumb the side control |
| Mounting | Planned magnetic back, or freestanding | Planned magnetic attachment | Adjustable textile strap |
| Count display | Ten plate-shaped markers (planned) | Single-number window (range under design) | Two-digit roller window (range under design) |

The origin
It started with a handful of rocks.
Our founder kept losing track of sets and rounds in CrossFit-style workouts. Not wanting a phone or a whiteboard, the fix was a handful of small rocks: one stone moved from one pile to the other after every completed set.
The motion was simple and oddly satisfying. The count became something you could see and touch. Rig & Rivet is the effort to make the premium version of that habit.

FAQ
Straight answers.
We haven’t announced a release date. When something real changes, the launch list hears first.
Can I buy these today?
No. All three are concepts in development. We haven't announced a release date. Join the launch list for development and launch updates.
Is joining the list a preorder?
No. There's no preorder, deposit or payment of any kind. Joining only means we'll email you updates about the concepts you choose.
What exactly do they do?
They track completed sets and rounds, not individual reps. Each concept is built around one physical motion: slide a plate, turn a ring or thumb a wrist control.
How firm are the prices?
They're expected launch prices: $49 for the Athlete Abacus, $59 for The Dial and $39 for The Wrist Counter. They may change after engineering and manufacturing quotes.
What are they made of?
Materials aren't final. The renderings show the design direction, not tested production parts. We'll publish real materials once engineering confirms them.
Why not just use an app?
Apps mean unlocking a phone mid-workout, with notifications waiting. A mechanical counter is one motion and one glance, and it doesn't need charging.
When will engineering be finished?
We don't have a date yet. Prototyping and mechanical validation come next, and we'll share honest progress with the launch list.
How high can they count?
The count range for each concept is still under design. The Athlete Abacus is planned around ten markers; The Dial and The Wrist Counter ranges will be set during engineering.
What will you email me?
Only updates about the concepts you chose: development news and launch timing. One confirmation email first, then messages when there's real news.
How do I unsubscribe?
Every email has an unsubscribe link. It opens a page with two buttons: “Unsubscribe”, or “Unsubscribe and delete my data” to remove your details entirely. Many mail apps can also unsubscribe you with their own built-in button.
